Dive into the structure and regulation of eukaryotic genes with detailed coverage of introns, exons, transcription, translation, and alternative splicing. Learn how genome organization varies across model organisms (E. coli, yeast, C. elegans, Drosophila, mice, and humans). These notes also explain research techniques like lacZ reporter assays, transposon mutagenesis, and DNA damage response screens—ideal for molecular biology, genetics, and bioinformatics students.
